NOTE:
1. A
0L — A14L ≠ A0R — A14R
NOTE:
1. There are eight semaphore flags written to via I/O
0 and read from all I/O's. These eight semaphores are addressed by A0 - A2.
NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS
may cause permanent damage to the device. This is a stress rating only and
functional operation of the device at these or any other conditions above those
indicated in the operational sec-tions of this specification is not implied. Exposure
to absolute maxi-mum rating conditions for extended periods may affect
reliability.
2. V
TERM must not exceed Vcc + 10% for more than 25% of the cycle time or 10ns
maximum, and is limited to
< 20mA for the period of VTERM > Vcc + 10%.
NOTES:
1. This is the parameter T
A. This is the "instant on" case temperature.
NOTES:
1. V
IL > -1.5V for pulse width less than 10ns.
2. V
TERM must not exceed Vcc + 10%.
NOTES:
1. This parameter is determined by device characterization but is not production
tested. TQFP package only.
2. 3dV represents the interpolated capacitance when the input and output signals
switch from 0V to 3V or from 3V to 0V.
